Thanks for the info in this topic, I have just one minor question (2 actually).
1: Do I have to setup the cover as 3 seperate switches with the appropriate commands for up/down/stop or can I set it up as a cover device and have all the build in features of home assistant?
2: I have a blind motor that has an upper and lower limit set and a middle position. On my remote I can push UP for 3 seconds to move the blinds to the upper limit, push DOWN for 3+ seconds to completely close the blinds and use a “MIDDLE” button to move the blinds to the middle position. It is a brel motor using the T6 protocol. Any clue how to implement this unit so I can use the limit positions and middle positions?

As I really don’t understand the translation between all the codes I can’t figure it out myself. I have managed to get the “down” code mentioned above working, it does correspond to a single press on the remote’s down button so I am positive that it could work, I am only wondering how to set it all up.

Never mind, I just figured it out (took a bit of luck actually). I added the cover with the code above, ending 0000 and set the signal repetition to 8 which seems enough to simulate a “long press”. The stop button in HA appears to correspond to my “middle” button on the remote :).

Hej Team,
I do have a hybrid solution with HA and Domoticz. In Domoticz I use the RFXTRX and all the devices are managed by HA via Curl or REST. Now I want to migrate everything to HA (5Blinds and 3 power sockets), but I totally truggle with the RFXTRX setup for the Device ID. I have checked the IDs with RFXmngr and tried to add this to HA, but it is not working. I already read:
ID: 0101015
Unit: 5
following device ids I tried for the covers:
091906000101010505
040201000101010505
071a00…
